Letters Patent No. 91,689, dated J mm 22, 1869.,

nmme FOR FIRE-PLACES.

The Schedule referred-to in these Letters Patent and. making part of thesame.

To whom it may concern Be it known that I, OHARLEs TRUESDALE, ofOincinnati, Hamilton county, Ohio, have invented a new and useful Liningfor FirePlaces, of which the following is a full, clear, and exactdescription, reference tion as to afford air-inlets between said blocksand frame, which, while preserving the said frame from destructive heat,are also effective for combustion and prevention of smoke. I i I Figure1 is a perspective view of a fire-plate lining embodying my invention, abinding-plate and one of the blocks being removed.

Figure 2 is a horizontal section of said lining at the line 2246.

Figure 3 is a section, showing my lining as applied to a cook-stove.

In place of the customary plain or corrugated lining of iron or othersubstance, I provide an open frame, A, of cast-iron,intersected bycross-bars B C, so asto' present a series of openings, D, to receiveblocks or panels, E, of soapstone, fire-tile, or other refractorymineral. V

The said bars and frame flare rearward, to receive thecorresponding]y-flaring or dovetailed edges of the panels, and are alsoarmed with protuberancos, b, so as to leave passages, c, forthe'entrance of'numerous minute currents of air, which, having absorbedheat from and cooled the bars A15 0, become effective to promotecombustion, and to prevent the formation of smoke. r

The panels E are preferably made so as to project somewhat forward ofthe fire-face of the frames, to protect the latter from direct contactwith the incandescent mass, and so as to afford channels (I for theentering air.

The air being permitted to pass in front of the panels, thereby preventsthe formation of clinkcrs upon them.

The panels being inserted, are held securely to their places by bindersl whose dovetailed extremities, f, enter and wedge tightly withindovetailed lips or ings G, on the rear side of the frame. The bindersmay have orifices f, to facilitate the passage of air.

-Tlfe said frame may have, at its lower edge, a gratitig, H, fortheadmittance of draught to the rear bot tom of the fire-place.

The top of the frame may have the usual flange I,

- for resting against the oven-plates.

Small panels, as represented, can be furnished at a nominal cost, andare less liable to be cracked or broken than if made of one'large block,and should one receive airinjnry,-it can be easily and cheaply replaced.

The binders are preferably stiffened with ribs or beads, as shown infigs. 2 and 3.

Although here shownadapted for the fire-back lining of acook-stove, theprinciple may manifestly be extended to the ends or otherwalls .of thefire-place, or to heating-stoves, or open fire-places. I claim herein asnew, and of my invention,

1. Providing the fire-chambers of grates, stoves,

8110., with'a lining consisting of a metallic frame, which i is adaptedto receive removable blocks of soapstone,

. fire-clay,-orother refractory Substances.

-2. Providing the fire-chambers of grates, stoves, 850., with a liningconsisting of a metallic frame, which is adapted 'to'receive removableblocks of soapstone, fire-clay, or other refractory substances, saidframe or blocks, or both, being either perforated, slotted, or otherwisearranged, so as to admit air into the firechamber proper, "substantiallyas herein described and set forth. V

3. The metallic frame A B 0, having openings 1), and protuberancesb,when used in connection with the removable block's E, for the purpose ofadmit-ting air, asabove explained.

4. The combination, substantially as described, of the metallic frame AB C,- rearwardly-tlaring openings 1), protnberances b, tapering blocksE, and one or more binders 1 or its equivalents, for the object stated.

5. Projecting the blocks E in front of theexposed 7 face of the metallicframe A- B0, as herein set forth.

In testimony of which invention, Iihereunto set my hand. a

CHARLES TRUESDALE.
